In March of 1963 it was announced that the Birmingham Parks Police were to be disbanded and replaced by a ranger service dressed in a distinctive green uniform. Officers expressed concern about losing their police powers and that they would lose their special payment of 36/- per week for loss of social life in the summer and their 3/- per week boot allowance. They also felt this action would lead to an increase in vandalism and inappropriate behaviour. The Council stated any existing member of the Force would not lose any pay, the only difference being a reduction of the boot allowance to 2/-, and that the new uniform would not affect their status. They also stated that the provision of radios and vans meant that any park could be quickly sent additional personnel and that this would act to reduce any perceived increase in unruly behaviour. It was, however, acknowledged they may be called upon to undertake gardening and labouring duties. At this time also the dispute over working hours was resolved. The Birmingham Parks Police had worked 52 hours per week in the summer and 32 in the winter. Under new arrangements the summer hours would be 44 per week and 40 per week in the winter.

On the 1st April a new force known as the Birmingham Parks Rangers came into existence. This change was not popular with staff as it was felt removing the title of 'Police' would impact on their status and make their role more difficult. New recruits were no longer attested, although those already serving retained their warrants, allowing them to exercise police powers. The service had 84 officers in 1963 and patrolled 406 parks along with a number of golf courses and other Corporation properties.

In November of 1965, Park Rangers met with their Union to ask that they approach the Council to have their powers of arrest restored. They also stated that a decrease in the number of dog handlers had led to a rise in vandalism. The request was denied by the Council.

In December of 1965 a petition signed by over 400 people was presented to Birmingham City Council calling for the Rangers to be given back their police powers. The Councillor stated the 70 strong force no longer commanded respect and called for the police uniform to be reintroduced to replace their current green ensemble.

The establishment had reduced to 49 by 1969 and a Park Ranger was paid £14 per week plus supplements for shift and weekend working which was comparable to Officers in the Birmingham Airport Police Force.

In February of that year proposals were put forward to replace the Rangers with a new mobile patrol force.

The uniform issued to Park Rangers differed from the one previously used in that the silver piping was discontinued and was green in colour. A new cap badge was introduced first in white metal and later in chrome, although many men continued to wear their former badge, a practise to which managers turned a blind eye. February of 1969 saw further reorganisation take place and on the 16th June the Birmingham Parks Rangers were succeeded by the Birmingham Parks Patrol that came into being.
